Due to the way it's been trained the input should be all lower case and punctuation removed. Use with . as the seperator between question and answer.

"where in the world is carmen. abruzzo" Output: "carmen is in abruzzo"

Thought punctation and upper case works.

from transformers import AutoTokenizer,  AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained('domenicrosati/QA2D-t5-small')
model = AutoModelForSeq2SeqLM.from_pretrained('domenicrosati/QA2D-t5-small')

question = "where in the world is carmen sandiego"
answer = "she is in abruzzo"
SEP = ". "

prompt = f'{question}{SEP}{answer}'
input_ids = tokenizer(prompt, return_tensors='pt').input_ids
output_ids = model.generate(input_ids)
responses = tokenizer.batch_decode(output_ids, skip_special_tokens=True)
# ['carmen sandiego is in abruzzo']

Intended uses & limitations

To convert questions, answer pairs into statements.
